A new movie about abortion.

The first thing you should know about the documentary “Lake of Fire” — an unblinking look at the violent fight over abortion in the United States, including those homegrown religious fundamentalists who kill in the name of God — is that it was made in black and white. This is critical. Because the other thing you should know about this fascinating, discomfiting, at times unpleasant, confused and confusing film is that it sets off extremely graphic images of actual abortions against a notorious photograph of a woman who died after an illegal motel room abortion, visuals that are inflammatory if, for the most part, also germane.
